The present invention relates to a transgenic pig that expresses sTNFR1-Fc, wherein a gene encoding sTNFR1-Fc, which is a fusion protein of the extracellular domain of human soluble tumor necrosis factor receptor (sTNFR1) and an immunoglobulin Fc region, is introduced; a method for preparing the same; an organ isolated from the transgenic pig; a somatic donor cell line inserted with sTNFR1-Fc gene; a method for preparing a blood sample comprising sTNFR1-Fc; and a method for preparing human sTNFR1-Fc from the blood sample of the transgenic pig. As the transgenic pig can suppress immune response and inflammatory response by secreting an inhibitory substance that suppresses the activity of TNF-&#x3b1; in blood, it can be effectively used for xenograft. Furthermore, since the transgenic pig has a blood type O, it can be transplanted for suppressing inflammatory response, regardless of a blood type of recipient.

Transgenic pig expressing sTNFR1-Fc genes and the uses thereof

The present invention relates to a method for producing a transgenic pig in which immune rejection response is inhibited, and in which human HO-1 genes and TNFR1-Fe fusion genes are simultaneously expressed. The present invention also relates to a transgenic pig for organ transplantation, which is produced by the method, and in which immune rejection response is inhibited. The present invention also relates to a somatic-cell-donating cell strain for producing the transgenic pig, and to a method for producing organs, from the transgenic pig, in which the immune rejection response is inhibited.
